Senior Software Engineer - React Native

Instinct Science • Doylestown, PA

1d • $150,000 - $175,000 • Remote

About The Position

Instinct Science is the AI leader in veterinary medicine — and we’re just getting started. Our platform combines a modern, cloud-native EMR with real-time clinical decision support and applied AI to transform how veterinary teams practice. Nowhere is that transformation more visible than in ScribbleVet.

Product Focus: ScribbleVet
ScribbleVet is our AI-powered scribe, built to eliminate one of the biggest drivers of veterinary burnout: documentation. What used to take veterinarians two hours at the end of a long day now takes twenty minutes. Hundreds of clinics rely on Scribble daily to generate high-quality medical records for thousands of patients.
This is not a side project. It’s a high-growth, AI-native product with real revenue, real users, and massive upside. We’re early enough to build from first principles — but far enough along to have strong product-market fit and customer love.
We’re looking for a Senior Software Engineer who wants to push applied AI into real-world healthcare workflows — and own meaningful problems end-to-end.
At Instinct Science, we believe in leading with compassion. Our team, our customers, and their patients and clients are the foundation of everything we do. Our culture is guided by our U.C.A.R.E. values, which serve as our daily compass:
Urgency: We move with speed because our mission is too important to wait. Urgency means prioritizing high-impact work, making timely decisions, and being highly responsive to our customers, partners, and fellow employees.
Customer First: We’re our customers’ (and this profession’s) biggest fans. We put them first and obsess over helping them solve their challenges.
Act with Grace, Not Teeth: We treat people with kindness, humor, humility, and assume good intent. We ask what we would want if we were in the other person’s shoes.
Right Things, Right Reasons: We take ownership of all tasks, big and small. When we make mistakes, we own them, fix them quickly, and learn.
Excellence is in our DNA: We hold ourselves and each other to high standards because our work is too important to do otherwise.
If these values speak to you, you might be a good fit for our Senior React Native Engineer job.
A Sneak Peek of Your Role 🔭
This role is remote (US-based) and embedded directly within the ScribbleVet product team.
As a Senior React Native Engineer, you’ll own the mobile experience end-to-end — from designing intuitive AI-assisted workflows to optimizing performance in real clinical environments. You’ll build and refine the React Native + Expo apps that veterinarians use during live appointments, where reliability, speed, and usability are mission-critical.
You won’t just implement tickets. You’ll help define how AI shows up on mobile — how prompts, edits, voice capture, visual diffs, and structured medical data feel seamless and trustworthy in a high-stakes setting.
This is high-autonomy, high-impact work.
